Mr. Marston, your question is extremely important. In 2000, at the NPT review of that year, the states parties grappled with the question of terrorists' use of nuclear weapons. They came to this conclusion, and they wrote it into their document, and all 188 states parties signed on to the following sentence: “...the only absolute guarantee against the use of a nuclear weapon is the elimination of nuclear weapons”. And that's the point we want to stress with the Canadian government that is today rightly concerned about questions of security. Among the Canadian government's concerns about security should be terrorist acquisition and use of nuclear weapons.
